Hello-<br><br>I might be missing something obvious, but I can&#39;t find any helper functions for converting a rotation matrix to a quaternion.<br><br>I made a rotation matrix by choosing 3 basis vectors and putting them into a btMatrix3x3 (or equivalently, a tf::Transform with 0 position offset).<br>
<br>I would like to just be able to just make a quaternion from this matrix. Does tf really not have a helper function for this? All I find are &quot;createQuaternionFromRPY&quot; sorts of functions, and Quaternion itself does not have a constructor that accepts a rotation matrix.<br>
<br>Thanks,<br>Adam<br><br><br clear="all">Adam Leeper<br>Stanford University<br><a href="mailto:aleeper@stanford.edu">aleeper@stanford.edu</a><br>719.358.3804<br>
